# OverlayModuleInfo
> **NOTE**
>
> The initial APIs of this module are supported since API version 10. Newly added APIs will be marked with a superscript to indicate their earliest API version.
The **OverlayModuleInfo** module provides information about a module with the overlay feature. A system application can obtain such information of the specified application through [overlay.getOverlayModuleInfoByBundleName](js-apis-overlay.md#overlaygetoverlaymoduleinfobybundlename), and a third-party application can obtain such information of the current application through [overlay.getOverlayModuleInfo](js-apis-overlay.md#overlaygetoverlaymoduleinfo).
## OverlayModuleInfo
**System capability**: SystemCapability.BundleManager.BundleFramework.Overlay
| Name | Type | Readable| Writable| Description |
| --------------------- | ---------------------------------------------------| ---- | ---- | ---------------------------------------------- |
| bundleName | string | Yes | No | Bundle name of the application to which the module with the overlay feature belongs. |
| moduleName | string | Yes | No | HAP name of the module with the overlay feature. |
| targetModuleName | string | Yes | No | HAP name of the target module specified by the module with the overlay feature. |
| priority | number | Yes | No | Priority of the module with the overlay feature. |
| state | number | Yes | No | Whether the module with the overlay feature is disabled. The value **0** means that the module is disabled, and **1** means the opposite. |

**Example**
```ts
var targetBundleName = "com.example.myapplication_xxxxx";
try {
overlay.getTargetOverlayModuleInfosByBundleName(targetBundleName, (error, data) => {
if (error) {
console.log('getTargetOverlayModuleInfosByBundleName failed due to error code : ' + err.code + ' ' + 'message :' + err.message);
return;
}
console.log('overlayModuleInfo is ' + JSON.stringify(data));
});
} catch (error) {
console.log('getTargetOverlayModuleInfosByBundleName failed due to error code : ' + err.code + ' ' + 'message :' + err.message);
}
```
## Module with the Overlay Feature
**Concept**
A module with the overlay feature generally provides additional resource files for modules without the overlay feature on the device, so that the target modules can use these resource files at runtime to display different colors, labels, themes, and the like. The overlay feature applies only to the stage model.
**How do I identify a module with the overlay feature?**
If the **module.json5** file of a module contains the **targetModuleName** and **targetPriority fields** during project creation on DevEco Studio, the module is identified as a module with the overlay feature in the installation phase.
